GRATE FOR FURNACES.

SPECIFICATION forming part of Letters Patent No. 352,692, dated November 16, 1886.

Application filed Ntvember 3, 1885. Serial No. 181,755. (No model.)

To all whom it may concern.-

Be it known that I, SILAS HYDE HUNTING- TON, of West Pittston, inthe county of Luzerne and State of Penn sylvania,have invented a new and useful Improvement in Grates for Furnaces, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 isaperspective view, partly in section,of my improved grate-bar. Fig. 2isa plan View, partly in section, showing two of the improved grate barsas arranged in a grate; and Fig. 3 is a transverse section taken on the line 00 m of Fig. 2.

My invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

In my improved construction Iform the sections of toothed end pieces, F, and bars G, cast integrally therewith, the bars G ofone section alternating with the bars G of the adjoining section, the ends of the bars being received in mortisesin the sides of the toothed wheels F. Each section of this grate-baristherefore made up of two wheels, F, and the bars G, projecting therefrom and 'nserted each in the mortiscs of the other vheels. The grate-bar is formed of a series of such sections placed on a hollow slotted shaft, H, and secured together by bolts I, passing through the entire series of sections, or in any other convenient way. The teeth of the wheels Fare'inclined in one direction, as in a ratchet wheel. The bolts which hold the series of sections together pass underneath the bars G. The pipe'J, inserted in the hollow shaft H, extends through the en- 7,

tire series of sections of the grate-bar, and is apertured to permit of the escape of the water. therefrom to the interior of the bar, to keep the bar cool and to furnish a certain amount of steam to the fire to improve the combustion and economize ffiel. I

A portion of agrate formed by a series of grate-bars of this kind is shown in Fig. 2. It will there be seen that the wheels F of adjacent bars alternate with each other, leaving space for the escape of ashes and clinkers, as in the other case. The clinkers areground up and removed by the rotation of the wheels F and of the bars G.

Having thus described invention, what I claim'as new, and desire to secure by Letters Patent, is- V I. The con1bination,in agrate-bar, of toothed wheels F, provided with bars G and mortises for receiving the bars of the adj oining section, hollow shaft H, andfastening-bolts I, substantially as herein specified. I v

2. The combination, in a grate-bar, of the hollow shaft H, the toothed wheels F, provided with the bars G, and the perforated tube J, inserted in thetubc H,substantially asherein specified.

3. In a grate-bar, the combination, with the hollow slotted shaft H, of toothed wheels F, provided with bars G, projecting from the side thereof, and provided with mortisesin the side thereof, alternating with the bars G, for receiving the bars G of the adjoining wheels F, and bolts I, extending through the entire series of sections formed of toothed wheels F and bars G underneath the bars G, substantially as herein specified.
